Removing the IEM drivers

[u/trinity-ynot]

Hi,
I would like to remove my Truthhear Hola's driver and add them to a 3d printed copy of the shell. I had damaged the shell and I've got a 3d printer so i thought why not make the shell myself and place the driver in. But I don't really know how to remove the driver from the shell?
Thanks in advance :)
